MACHINE FOR MAKING AND ATTACHING TYPEWRITER-RIBBON CLIPS.

Application filed December 27, 1922.

To all whom it /nmy/ concern.'

Be it known that I, HUBERT MCL. ARMI- s'rEAn, a citizen otl the United States, residing at the city and county of San Francisco, and State of California, have invented certain new and useful Improvements in Machines for Making and Attaching' rlypewriter-Ribbon Clips, of which the following' is a specilication.

My invention relates to the preparation ot' impression ribbons for certain uses in tonnection with typewriters and like type impact machines, adapting them for ready Connection, by making' and attaching their gccuring' clips. In the manifolding art by mf'eh typing machines are made capable 'Ol'l producing' a plurality ot copies, an approved practise comprises the association with the machine of one or more short lengths of manifolding' ribbon, carried by movable members by which they are adapted to be placed between the sheets of paper, in functional position in the line of type impact. The ends ot the ribbon sections are litted with clips by which their attachment to the carying members may be readily ef'i'ected and the sections held nuclei' proper tension. A ribbon section of this kind with its end clips is disclosed in Letters Patent of the United States No. 1,420,874, dated .lune 27, 1922, and as my invention concerns especially this ribbon, and consists in a novel machine jlfor making and attaching its end clips, l have herein illustrated said ribbon, apart from the machine, in Figs. 416 to inclusive, on Sheet l() olf the drawings, and shall describe it in sufficient detail to insure a ready umlerstanding of my machine and its several functions.

one end 0f the completed ribbon, showing the cli-p secured thereto in its `final form.

Referring first to Figs. 50, 51 and 52, on

Sheet l0, the ribbon isV indicated by A and the clips by B. The clips may be made of metal, fabric, paper, or other suitable bendable material, Vthough in practise, paper for many reasons is preferred. The blank from which the clips B are formed, as initially stamped or cut out is shown in'V Fig. 46- and Y comprises a body portion b, two-flaps b projecting from one side and sepa-rated by a slot b2and two other flaps b3 extending from 'the other side. The flaps b3 are at the ends of the blank, vWhile the flaps o lie between and back of the ends. The clip blank is gummed ila-t; as shown, on Vthe .stripv A1 from `which the ribbon A Ais subsequently cut, and two` converging lines of 'holes 'b4 are made inthe body portion Z)- i extending inwardly from the -outer angles o'fftheiiaps Thesefholfes centinueIthroug-h the ribbon itself as shown inlligs'.` 47 and 48'. lfn- Fig. 47' the ribbon sideuofthe gummed' assembly of Fig. 46 is shown. The ribbon hfas been cut on--a diagonalfbetween'thefla-ps A bv ofa previously gummed clip blank, leavino. the end as'shown at theV right with a tabI a, While at the left appears a-succeeding complete-'clip-blank.

In 'Fig.'48 the ribbon tab 0f `at'the right hasbeen cut olf on a -reverse diagonal, while at the left the ribbon is cut asshown on'a4 diagonal similar to4 the diagonal which formed the rig-ht end tab af in Fig. 47. Thus there remains'asshownin Fig'. 48a single orunit length or section of ribbon',each endi having gummed"y to it one half of a=clip blank, and being trimmed preparatory to folding.

In Fig. 49jthe1f1aps` b and theends-ofthe ribbon have been foldedover on the dotted lines a-a of F ig. 48 through the lines of holes byand the flaps b gummed down, thus forming` the diagonalnotched crease fold Z5? for the reception of the carrying' members to; which the cli-ps are to be secured, as set forth in saidYPa-tentNo. 1,420,874.

11n Bug-..50y the other flaps b3 have been fol-ded over andgummed down, thus form-ing vthe completedv clip ends, one ofj which is further shown in'Figs. 5lY and 52.

Referring, for the moment, tol Fig.f32.

on Sheet 8 of the drawings, the paperor other material from which the clip blanks b offF ig. v46 are stamped, is fed into the machine from the rear in the .for-In of a continuous and previously gummed strip B. ,while the ribbon, also in the form: of a continuousstrip A, is fed` in. fromthe side, at Vright anglesto the strip B ,At the position indicated by C the-first operation, via-stamping thel double cl-ip blank, pressing it upon the ribbon, and punching the holes b4, with the result shown in Figf46, is performed by the mechanism illustrated in,l detail iii-Figs.- l to 114' inclusi-ve.4 This operation is performed successively, at; properly spaced intervals on the ribbon strip A, and said ribbon strip, with the clip blanks attached thereto, then travels on to the position l) of Fig. 32, where the succeeding operations of cutting and folding its ends, as shown in Figs. 47 to 5t), are performed by mechanism illustrated in detail in Figs. 15 to 31 and 33 to 45, inclusive.

Turning now to the blank stamping mechanism at the position C of Fig. 32, the clipblank stock or strip B is carried in a coil or reel previously wound upon a mandrel 1, Figs. 1, 10, and 11, and said mandrel is journaled in trunnion'blocks 2 which are vertically slidable in guides 3. The coil of paper strip B rests upon an idler roll 4, Figs. 10 and 11, and said strip is passed first between a pair of continuously rotating feed rolls and is then looped as at (S, to accommodate the necessary slack, and is subsequently passed between a pair of intermittently rotating feed rolls 7 and 7 thus providing a steady feed from the coil, to prevent said coil from running ahead, and at the same time providing a properly timed intermittent feed tothe stamping die.

The feed rolls 5 and 5 are continuously rotated by means of a sprocket 8, Fig. 10, z'secnred to the shaft of the lower roll 5 of the pair, and said sprocket is connected by a chain 9 with a sprocket 9 secured upon a horizontal shaft 10, which is connected by a chain 11, Figs. 1, 3 and 11, with a horizontal shaft 12 journalled at the top of the machine. The shaft 12 is driven by worm gearing 13 from the shaft of a motor 14, as shown in Figs. 1, 3, and 11. This motor also supplies the power for operating all other parts of the machine, as will be described hereinafter. The intermittent feed rolls 7 and 7 are driven by a gear 15, Figs. 1 and 11, fixed upon the shaft of the lower roll 7 of the pair, said gear meshing with an idler gear 16, which in turn, is driven in a step-by-step motion by a Geneva mechanism 17, Figs. 1, 3 and 11, from the continuously rotating shaft 10. The upper feed rolls 5 and i" are driven by frictional contact with the lower corresiionding rolls 5 and 7.

The clip blank strip B is pushed by the intermittent feed rolls 7 and 7 into a guideway formed between the fixer die 1S and an overlying guide plate 19, as shown in Figs. 3, G, 7 and 8. The die 18, shown in plan in Fig. 6, has an aperture of the form of the clip blank as described above and illustrated in Fig. 46. Said die. and the guide plate 19 are spaced above a bed plate 21, and are removably secured thereto by means of bolts or screws 22, Figs. G and 7. The ribbon strip A. is fed through, immediately above the bed plate 21, at right angles to the direction of the clip blank strip B', as shown by the dotted linesI and arrows in Fig. 6. Said ribbon strip thus lies below the clip blank strip, as shown in Fig. 7.

The supply of ribbon strip A. is carried as a coil, Fig. 1, wound upon a mandrel 22S which is carried by trunnion blocks 24 vertically slidable in guides 25, and said coil is supported, in a manner similar to the coil of clip blank strip B described above, by an idler roller, not shown. The ribbon strip A is passed between a pair of continuously driven fed rolls 26 and 26, Figs. 1 and 3, to provide a steady feed from the coil, and is then looped as at 27, and passed between a pair of idler rolls 28. The lower feed roll 26 is continuously driven by spiral gearing 29, a horizontal shaft 30, and spur gears 31 from the continuously rotating shaft 10. The upper feed roll 26 is driven by frictional contact with the lower roll 26.

After leaving the idler rolls 23, the ribbon strip A is drawn through above the bed plate 21 and below the die 18, by a pair of intermittently rotated feed rolls 32 and 32, Figs. 1, 2 and 3 positioned at the opposite side of the machine. The roll 32 is driven in a step-by-step motion, by spiral gearing 33, Figs. 1, 2 and 3, from a short horizontal shaft 34, which in turn driven by a Geneva mechanism 35, Figs. 1, 3 and 10, `from the continuously rotating shaft 10. The upper roll 32 i's driven by frictional contact from the lower roll 32.

The punch 36 cooperating with the die 1S for forming the clip blanks is carried by the lower end of a plunger 37, Figs. 3, 4 and 5, which reciprocates vertically in guides and is operated by an eccentric 39 on the upper horizontal shaft 12. Said punch, whose working face is shown in Fig. 9, is fixed to a plate 36', which in turn is secured to a central pin 40, Fig. 7, which is slidably mounted in a socket formed in the lower end of the plunger 37 and pressed downward by a spring 41. Bolts 42, fixed in the punch carrying plate 36 and passingl freely through a flange 37 at the lower end of the plunger, serve to limit the downward movement of the punch with respect to said plunger, and also to prevent it from turning.

The punch 3G has formed in it six vertical holes 43, as shown in Fig. 9, positioned to correspond with the holes b4 in the clips and ribbon, as described above and shown in Fig. 46. Hthin each of these holes 43 is a punch or rod 44, Figs. 7 and 8, said rods being held firmly against the flat lower surface of the plunger flange 37 by springs 44, as shown in Fig. 8, and slidable in the holes 43 of the punch 3G. The rods 44 are of such a length. that their lower ends are flush with the bottom of the punch 3G when the latter is in its normal position, as shown in Fig. 7. The bed plate 21 is provided with holes 45 corresponding in position to the holes 43 in the punch.

'Ihe downward movement of the plunger out a clip blank from the strip Br lying immediately above the die 18, and then pushes the cut blank down through said die, pressing ituponthe ribbon strip A lying upon the bed. plate 21. The plunger then continues'its downward. movement for a sutlicient distance to cause the rods 44 to punch the holes b4 through both. the blank 7a and the ribbon strip Ai', as shown in Fig.

8, the punch 36 remaining stationary andv the spring 41 contracting during thisffinal stage ofthe movement ofthe plungerl 37. The plunger then returns to its upper position, as shown in Fig. 7, and the Yclipblank strip' B and. the ribbon strip A are advancedthe necessary distance by their respective feed rolls described above, and the operation is complete. v

Thev clip blank strip B has been previously gummed, as before stated',and is fed into the machine with the gummed. side down. In order to cause the` cut blank to Yadhere to the ribbon strip A', said ribbon blank and the pressing thereof upon saidV ribbon. y y Y f For this purpose there is provided in front of the vbed plate 21; a water container 46, Figs. 3, 11, 12 and 13, in which. is jou'rnal'ed a roll 47. Said` rol-ll is continuously rotatedv by means of a' pair of spur gears 48, Figs. 3. and 10, and ai. chain 49, from the shaft 10. The chain 49 is, in reality, continuous with.v the chain 9, asshown in Fig. 10, the lower run passing under the sprocket9 and the upper run passing under an idler 50. 1

The water is transferred fromtherotating roll 47 to the ribbon by a smaller roll `51, Figs. 11, 12 and 13,. mounted on a carriage 52, andv adaptedV to bev moved rearwa-rdly, into. the space between the die 18- and the bed. 21, by anv arm 53,` Figs.10, 11= and .112; whichV is carried by an oscillatory shaft 54 andV has a roller 55 adapted to`- follow a cam 56, Fig. 10, lixed upon the sha-ft 10. Y The transfer vroll 51` is normal-ly., held in contact with the rotatingwater roll 47, asshown in Fig... 12 and in dotted lines in Fig.l13`, by springs 57, Fig. 3, positioned at the ends of the shaft 54 of the cam 53,

ii and is mov-ed rearwardly by thel cam 56 and the arm. 53, over the bed 21 and thcsurface of the ribbon strip A, tothe posit-ion shown in full lines in Fig., 13, and immediately returned to its normal position before the downward movement of the clip blank stampin-gpunch.; A spring 58, Figs.v 1-2 and 14, is provided to insure contact between the transfer roll 51 and the ribbon strip A and the water rolly 47. Y l Y The ribbon strip A with the clip blanks secured to its'V upperl surface at regular intervals, passes out of the mechanism describedr above, which as before stated is located at the position. C ofthe dia-gram, Fig. 32, andi enters the mechanism indicated lby D; which isy shown in detail inE Figs. 15 to 31 andr 33to 45 inclusive, and which will now b e described. l

rEhe ribbon strip A enters this mechanism from;y the left of Fig. 15,. which is a rear elevation, or from the right of Fig..V 31, which isfa front elevation, as indicated by the dotted line and arrows. At the extreme left of Fig. 15 are shown thel intermittent feed rolls 32 and 32 described above and shown in F iigs.. 1,. 2V and. 3. Leaving these rolls, the ribbon strip A is loopedk at 59- toy provide necessary slack, and is passed between a pair ofi'dler tension rolls 6.0, the upper; one of the pair bein-g carriedby a spring bracket 60, Figs. 15 and 31, then over a guide roll 614 andv under a second guide roll 62, and across. the machine to a .pair of continuously driven feed rolls-63 and Y ,i

63. VFrom these thev ribbonI strip A. is looped, at 64, to prov-ide slack, and is then inverted and carried back into'the machine through a pair of tension idler rolls 65V mounted in a spring bracket66. 1 Theribbon 1 strip is thus carried into the operative portion of the machine with the clip blanks on its under surface, in order to provide for the folding of the flapsfof said blanks as will be hereinafter described. Y.

.The feed roll 63-is xed vuponfashaftv 67, Figs. 15 Vand 31, which is continuously driven by a pair of bevel; gears 68, Fig. 20, Jfrom a shaft 69, which is extended from` the clip blank forming mechanism described above; Said; shafft 69, as shown in Figs. 1, 2: and 3, is dri-ven by a pair of spur gears 79v from the continuously Vrotating shaft-'10; The upper roll 63 is driven from the lower v roll 63' by frictional contact therewith.

The end portion of the ribbcnsstrip A', after passing through the tension rolls- 65,

Figs. 16, 17 and 19, secured toa bracket 73 horizontally adjustable on a` pair of tixed- Q transverse guide rods 74, Figs. 15, 16 and 17.V A sliding bracket' 7 5 is also mounted on said guide rods, andy is reciprocallyinoved across vth-e machine by a link 7 6, Figs. 15, 2O and 31,l and a lever 77,. the latter bei-ngY pi-votedat 7 Sand connected by a pitman 79 with` a crank disk 80. The pitman 79 is adj'usltably connected with thel lever 7 7 by means of a slot 81 .in the latter, Fig's`.15 and 31,. topermit. the length of the stroke,y and consequently thev length of; travel of the bracket 75, to `bevaried. The crankdisk S0 is fixedA` uponv a sha-ft 82,' Figs. 15a-nd 20, which is: rotated intermittently. meansof spur gea-rs 83 and bevel gea-rs84, Figs. 1, 2 andk 20, from the intermittently rota-ting lill) shaft 3l described above.A By means-of this mechanism. 'the bracket' 75 is periodically moved from the rposition rshown in Fig. 15 and `in full `lines .inFig 17, Vto ythe position indicated by the dotted lines in Fig. 17, and then back to its first lposition.

ylhe movable bracket 75 `carries a spring` clipS, formed as shown in Figs.16,17 and 1S. Said clip has lpair of earsv 86',- which ride over a strip 87 secured to the fixed bracket 723,' thereby lifting` the -endof said clip when said movable bracket 75 approaches-said'fixedbracket. This allows the end'a. ofthe ribbonstrip A to enter between said cli-p S5 anda friction pad 85 secured to the bracket 7 5. The ears .86 vof said. 'clip 'then pass the inwardly turned ends of the trip S7, and said clip descend-s, clamping the endo of theribbon :strip between itself and the pad S5. On the return movementfof the bracket 75, the trip yS7, which is pivotally mounted atS7, rides up over .the-.ears 8G of the clip 95 without raising said clip, so that the ribbon strip ii'emain-s clamped thereby and is drawn forwardly, as shown bythe dotted lines in Fig. 16, a distance equa-l to 'the length of one complete ribbon section.

yThe poritionof theribbon strip A which is thfus drawn across-the machine lies upon a carriage v8S as shown in F 24k, and is so positioned 'that there is a clip blank Z) at each end of said carriage. One section of the blank b at the left of Fig. 2i has been cut in the previous operation, but a com` plete double blank is shown at the right. 'the carriage 8S is provided with lineally adinstable lend portions S9, one of which is shown in Fig. 28, and said end portions are l'novided with shallow grooves 89 within wl-iich .the end portions of the ribbon lie, and with inclined faces 90 at their ends, Figs. 2i, and 28, 'which cooperate with inc-lined cutting knives, to be described later, for shearing or cutting the ends of the ribbon.

The carriage 8S supports two vertical `guide rods 91, Figs. 15,. 20, 23A and 31, onek near each end. Fach rod.91 has mounted on it a. movable slide 92, Fig. 31. rlhe slides 92v are lioined together by a cross bar at their upper ends, and are norm-ally held in their uppe-rn'iost positions`r as shown, b5' springs 9st. The. slides are also connec-ted by horizontal guide rods which in turn carry a pair of horizontally movable slides 9G, which are normally held in their innermost positions, as shown, by springs Each horizontally movable slide 9G car-` ries a spring'presser foot 9S: Said presser feet are so positionedas to be brought down upon the ribbon. as it lies upon the carriage 88, by the downward movement of the slides 92, and subsequently spread-apart, to smooth and stretch the ribbon. by the out-ward or separating` movement of the slides 96. Figs.

15, 20, 23' and Sil `show the presser feet 98 in their inoperativeposition, Figs, 24 and 26 showvthenriV after their .iii-st, or downward movement, andFigs. 25 and 27 show them after 'their second or horizontal movement, the, ribbon being stretched and held fiat upon the carriage 88.

The operation of said presser feet 9S is showtnmore vclearly :in Fig. 33, wherein the left hand view shows the ribbon strip A lying within the groove 89 `of :the carriage S8 and the presser foot 98l in its elevated or `-11ormal position. ln the lcentral view the presser foot-98 has descended upon-,the ribbon, and in the yright hand view `the presser foot 9S has agai'nlifted v"and the ribbon hasA been removed. f

This figure also illustrates the movement of 'the carriage-88 itself, 7asvwill be later described. The ends of the presser feet 98 are. pointed, as shown in Figs. 24e Y'and to conform to the inclined ends 90 of the carriage 88 and 'the first fold of -the ribbon end and clip blank, on the line c-a of F Ll-S as described above.

The slides 92 are moved downwardly, to bring the presser feet 9S down upon the ribbon, by means of a roller 99 lcarried by the upper cross bar 93, Figs. and 23. Said roller eng-ages a cam 100, which is elongated, as shown in Fig. 28, to permit fore and aft motion of the carriage S8 for purposes to be lset forth hereinafter. Said cam is rotated intermittently by `a rearwardly extending shaft 101, Figs. 28 and 31, a chain 102, and a Geneva mechanism 103, Figs. and 351, which car-ries the sprocket102 for said chain, said Geneva mechanism being driven by a pair of spur gears 104, Fig. 20, from the continuously rotating shaft 67.

The slides 96 are operated, to separate the presser feet 98 after they Ahave Abeen moved down by the above descri-bedfmechanism inte contact with the ribbon, by means of cam following rollers 105, Figs. 15 and 20, which are engaged by acam 1:06. Sai d cam is sliclable upon a feathered shaft 10T- Fig. 23. The followers 105 are flanged, as shown, to cause said cam to slide along its shaft 107, to accommodate itself to the above mentioned movement of the carriage. S8. The cam shaftr 107 is inter1ni..;ently rotated by a chain 108, Fig` V31, and a. Genevay mechanism 109, Fig. 20, which can ries the sprocket 108 for said cha-in. Said Geneva mechanism, asl shown in Figs. 20 and 34, is concentric with the Geneva mechanism 108, the driving members of both being mounted upon opposite sides of a common disk 109, which is driven by the spur gears 104.

After the ribbon strip has been clamped upon the carriage 88 by the presser feet 98, it is cutI off, to forma unit section, along the lines of the inclined ends of said-carriage, as shown in Fig. 25, by vertically movable knives 110, Fig. 15, carried by the lower ends of rods 111, Figs.. 15 and 20, which slide in guides 112 carried by the frame of the machine. The knives are adjustably secured to the rods 111, to permit variation in the length of the ribbon cut, as shown in Figs. 29 and 30, each rod 111- being provided with a foot 113, to which the knife 110 is secured by a tongue and groove joint 114 and a clamping screw 115. The rods 111 'are normally held up by springs 116, Figs. 15 and 31, and are moved down, to cause the knives 110 to cut the ribbon, by a cross yoke 117 provided with a roller 118, Figs. 15, 23 and 31, positioned to follow a cam 119. Said cam is intermittently rotated by a chain 120, Fig. 23, a pair of bevel gears 121', and a Geneva mechanism 122, Figs. 21, 22 and 23, the driving: member of said Geneva mechanism being mounted on the continuously rotating shaft 69.

After the unit length of ribbon A has been cut off, and while it is still held on the carriage 88 by the presser feet 98, as shown in Fig. 25, said carriage, andthe presser foot mechanism associated therewith, is moved-bodily toward the front of the machine, or toward the right as viewed in Fig. 23. To accomplish this movement, the carriage 88 is slidably mounted on hori- Zontal guide rods123, Figs. 15, 2O and 23, and is connected by a link 124 with a, crank disk 125. Said disk is intermittently rotated, at the proper times, by bevel gearing 126, Figs. 15 and 20, and ak Geneva mechanism 127, the driving member of the latter' Abeing fixed upon the continuously rotating shaft 67. This forward movement of the carriage 88 and its associated parts, 1

which carries them from the position shown in full lines in Fig. 23 to that shown in dotted lines, effects the folding of the ends of the ribbon A and the flaps-Z9 and b3 of the clip, as outlined above in connection' with Figs. 49 and 50 of the drawings.

The first operation accomplished by the forward movement of the carriage 88 is the moistening of the upper ginnmed surfaces of the clip flaps b and'bg, which lie in the position shown in Figs. 25, 37, 43 and 48. For this purpose there are provided two fixed brackets 128, Figs. 20, 23 and 3G, one positionedover the path of travel of each ond portion of the ribbon A as it lies on the carriage 88. Each bracket 128 supports a water container 129, Figs. 23 and 3G, in which is a rotatable roll 130. A forwardly extending swinging bracket, shown at 131 in Figs. 36 and 37, is pivotally mounted about the shaft of said roll 130,' and said bracket carries two rotatable water rolls 132 and 133, and a cam follower 134. The rolls 130, 132 and 133 form a train, asshown,

passing over pulleys 132 and 133, respectively, mounted on the projecting ends of .the shafts of said three rolls. The cam follower 134 is positioned to ride upon the Y under surface of a cam 136 secured to the carriage slide members 92 and 93, as shown in Figs. 15, 20 and 23, and therefore movable forwardly with said carriage. This causes the bracket 131 to be depressed, `to the rposition shown., in dotted lines in Fig. 36, so that the roll 133 bears upon the upper surfaces of the clip flaps b1 and '63, and transfers its moisture thereto, as the latter are carried forwardly by the carriage '88 beneath'said roll. The rotation of all three rolls 130, 132 and 133 is effected by the frictional contact between the carriage and the roll 133. Aspring 137 normally holds the bracket 131 in the position shown in full lines in Fig.'36. Y i

, After passing beneath the moistening roll 133, the continued forward movement of the carriagel 88 causes the clip flap to be e11- gaged by a stationary folding blade 138, Figs. 37 to 40, inclusive. The ribbon end is still held in the groove 89 of the carriage 88 lby the presser foot 98, as shown in Fig. 43, although said presser foot has been omitted from Figs. 37 to 40, in order to show the ribbon beneath. This causes the clip flaps b and?)3 to be slightly elevated, by the shoulders of the carriage groove 89, as shown in Fig. 45, so that said flaps may be engaged by the folding blades. The fixed folding blade 138, which has an inclined end, as shown in Figs. 37 to 40, therefore engages the iap b', as the carriage passes beneath it, and folds said -flap b and the end of the ribbon A over on the line if-a., this line corresponding with theend of the presser foot 98, as shown in Fig. 43. This results in the condition shown in Figs. 39 and 49, and described at the beginning vof this specification.

At the same time, a pin 139, Figs. 15 and 38 projecting downwardly from the carriage 88, engages a slot 140, Figs. 38 to 41, in a horizontally swinging arm 141. Said arm is pivotally mounted upon a stud 142 and has connected with and spaced above it a movable folding blade 143. Thus the forward movement of theV carriage 88 causes the movable blade 143 vto swing 'forwardly from the position shown in Fig. 38, through that shown in Fig. 39,'to'its final position .w

as shown in Fig. 40, and to engage the clip flap 'Z13 and fold the same over, as shown. The movable blade 143 is positioned to immediately overlie the Xed blade 138, as shown in Figs. 39, 40 and 42, and its moveiso j ment is so timed as to cause it to engage the flap b3 immediately after the flap b has been folded over, as shown in Fig. 89.

Thilo the flap b3 is being folded over by the movable blade 143, the presser foot 98 is withdrawn, by its operating mechanism described above, from the position shown in Fig. 43 to that shown in Fig. 44, and, at practically the same time., the carriage 88 comes to rest beneath a presser roll 144, Figs. 86 and 8T. Said presser roll is mounted on a spring bracket 145, and bears upon the fixed and movable blades 188 and 143 respectively, and, through them, presses the folded clip B against the carriage 88 with sutlicient force to cause the proper adhesion of the flaps 3) and b3, resluting in the linished ribbon as shown in Fig. 50. It should be again noted that the moistening, folding, and pressing mechanism described above and numbered from 128 to 145 inclusive, is duplicated at the two ends of the-machine, as indicated in Fig. 20, so that both ends of the ribbon are finished simultaneously.

The carriage now begins its rearward, or return movement, the pins 189 returning the movable. folding blades 148 to their normal positions.. During this return movement of the carriage, the presser feet 98 are also lreturned to their normal positions, leaving the finished ribbon lying freely upon the carriage, and said ribbon is engaged and removed from said carriage by a finger' 146, Figs. 20, and 8.3. Said finger is pivotally mounted at 14T upon a vliked support, and has a beveled tooth 148 upon its forward end, so that it rides up over the carriage and ribbon upon their forward movement, but engages said ribbon 'and removes it from the carriage upon the rearward return movement of the latter. The finished ribbon then falls to any suitable place of deposit not shown in the drawings, and the carriage returns to its rearward position in readiness for the. reception of the next succeeding length of ribbon strip. Thus the cycle of operations is complete, and the parts are in position for a repetition of the operations as described.

The necessary parts of the machine, are adjustable, within certain limits, to enable it to attach clips to ribbons of slightly greater or .less length. The. bracket 78, Fig. 15, as before stated, may be shifted along the guide rods T4, and the stroke of the sliding bracket T5 may be correspondingl)Y varied by shifting the connection between the pitman 79 and the lever 7? in the slot 81. The effective length of the carriage 88 may be varied by shifting the grooved end portions 89, Figs.

and 28 upon said carriage, and the cutting knives 110 may be shifted upon their carrying rods 111 to correspond, as shown in 29 and fit). 'llo accommodate such adjustments, the ribbon strip feed rolls 26 and 26 of Figs. 1, SZand 82 and 68 and G8 of Fig. must be replaced by similar rolls of the proper diameter. 1

A brief resume of the operation of the machine may conduce to a better understanding' of the foregoing description. The clip blank strip B and the ribbon strip A enter thc machine, at the position C of Fig. 82, at right angles to each other, the clip blank strip being above and the ribbon strip below. Both are fed intermittently, the clip blank strip B advancing a distance equal to the. width of a blank at each motion, and the ribbon strip A advancing simultaneously a distance equal to the length of a completed ribbon section A. During each period of rest of the two strips B and A, the mechanism' at the position C stamps a clip blank from the strip B and presses it. flat, upon the upper surface of the ribbon strip A. rllhe blank strip B, it will be remembered, has been previously gummed upon its under surface, and the upper surface of the ribbon strip A is moistened, immediately prior to the stamping of the clip blank, to cause said blank to adhere to said ribbon strip.

rllhe ribbon strip A, with the clip blanks secured at regular intervals thereto, then travels on to that portion of the mechanism located at the position D of Fig. 82, and is inverted to bring the ribbon strip above the blanks. Said ribbon strip is drawn into this mechanism by the reciprocating slide bracket 75, which advances the strip, at each stroke, a distance equal to one complete Yribbon length, and lays the portion thus drawn out upon the carriage 88, as in Fig. 24. This portion of the ribbon is then. clamped upon said carriage by the presser feet 98, and its ends are cut off by the knives 110, leaving the ribbon length A with approximately one half of a clip blank at each end, as shown in Q5 and 48.

The carriage 88 then moves forwardly, causing` the moistening, folding and press ing of the clip i'iaps i5 and 3 as described. resulting in the completed ribbon as shown in Fig. 50, which is removed from the carriage 88 during the return of said carriage to its normal position. The driving mechanism of the machine is so constructed that these operations occur in a fixed phase relation to the stan'iping of the clip blanks from the blank strip B, so that for every such blank formed and applied to the ribbon strip A at the position C of Fig. 82, one ribbon length A is cut and has its clip ends folded at the position D. The ma# chine, when once set in operation, is entirel;r automatic, its various functions being repeated, in the same sequence and time relation, as lone' as the strips A and B continue to be suppiied and the driving motor 14 is energized.
